NGK (1675) PFR7S8EG Spark Plug - Pack of 4

So, there are some really good fakes out there. There are ways to determine if what you get is legit or not. Looking over the boxes, plugs, machining, etc. These are real. A really good way to determine if they are genuine is to take a multimeter and shoot for resistance through the spark plugs. They should have values within 10% of each other. I tested my spark plugs I received and they read anywhere from 1.38-1.44 ohms, well within the threshold of a genuine plug. I wouldn’t hesitate to order from this buyer again and I would still check for knockoffs either way.

Works as intended-be sure to measure the plug gap before install-no fouling or or pinging/knocking (assuming you installed properly and use quality gasoline)-car feels more smooth during acceleration upon install-gas mileage somewhat restored after installation (note: gas mileage depends on many factors)

Perfect

As mentioned gaps can be off on some plugs. I re-gapped them all to .31 and right away could tell the difference in power and shifting. Good plugs. I've seen multiple gaps out there from .28 to .32 for B'7 and decided to go closer to .31 since I'll replace the plugs sooner then later. Last time I used Bosch and I think I prefer NGK. Cold starts were for sure quicker too. If you don't know how to gap a spark plug get a tool, it's simple.

Replaced these myself as part of the 35k recommended service on a B8 allroad. Pretty easy to do. I did research on the proper replacement plugs and these were closest to factory recommended. You can take my word for it or do the research yourself. Lots of pages of platinum vs. iridium and NGK vs. Bosch vs. others. I feel that plugs are changed so infrequently that it's just not worth it to mess around with anything new or slightly different than recommended, as any performance difference would be negligible. I didn't have any issues before or after the change so no performance change to speak of nor was any expected.
